Traveling Significant others?

What does your significant other do while traveling?

My fiance and i are dreaming about traveling in a few years. The problem is that i do not have a skill that is travel friendly. I have been thinking of a career change for the last few years, but can't come up with anything that would be travel friendly. I do have some time to get through a college course, so i have spent days staring at what the local colleges offer trying to figure out what would work for me to no avail.

I have thought about nursing to work along side her, but I don't know if I'm cut out for the trials and rigors of what you all do. I thought about being an xray tech for a little while, but i just don't think i would be able to handle any medical career.

So what jobs do your SO's hold that can keep up with your ever changing location, and still be able to have some time to enjoy the travel experience?
Thanks for your time.
